Patent JP-H089677-A (JP)
Title: Motor control apparatus
Inventor: MATSUO JIYUNKOU
IPC: H02P7/29
Filed: 1994-06-21
Abstract: PURPOSE:To make torque change always constant by controlling a PWM frequency even when the torque change is increased due to a speed by a method wherein a pulse width modulation frequency variable means is made variable according to the speed of a motor. CONSTITUTION:A load 33 is constituted as an optical system, and a DC motor is used as an optical system scanner motor 32. In this case, when a CPU 30 which controls a copying machine inputs a PWM signal to a drive circuit 31 in order to drive the optical system, the PWM signal makes a current flow to the motor 32 only during the time at a high level out of cycles. Consequently, a motor current, i.e., the number of revolutions of the motor, can be controlled by the PWM signal. In addition, the number of revolutions of the motor can be detected when a rotary encoder signal (an RE signal) is fed back to the CPU 30 from the motor 32, and the rotation of the motor is controlled by using it. As result, even when a torque change is increased due to a speed, the torque change can be made always constant by controlling the PWM frequency.

Title: Zero crossing detector for ac power source
Inventor: SHIROSUGI KOJI
IPC: G03G21/00
Filed: 1998-05-06
Abstract: PROBLEM TO BE SOLVED: To make control of an exposing lamp control, fixing heater, etc., with an AC voltage possible by using a stable AC power source, by detecting the zero-crossing point of the AC power source and controlling the AC voltage output of the power source by using the zero-crossing point as a trigger. SOLUTION: The zero-crossing point of an AC power source 6 is detected by means of a zero crossing detecting circuit 16, and the frequency of the power source 6 is detected by counting the detected zero-crossing point for an arbitrary period of time. Then the output signal or time synchronous to the zero-crossing point is measured during a period of time (1/detected frequency)-α based on the detected frequency. Thereafter, the AC voltage output of the power source 6 is controlled by means of a CPU 8, drivers 9 and 10 for control, and triode AC switches 10 and 12 by using the zero-crossing point as a trigger.  Since no program processing is performed while a zero-crossing point managing signal is outputted or during zero-crossing point managing time, the output control (exposing lamp control, fixing heater control, etc.), by means of a regular zero- crossing point can be performed.
